If you have further questions you may contact the Safe Drinking Water Hotline, which provides information about EPA's drinking water regulations and other related drinking water and ground water topics:

You may also want to contact EPA’s Asbestos Abatement/Management Ombudsman or Toxic Substances Control Act (TSCA) Hotlines. The Asbestos Ombudsman provides information to the public sector, including individual citizens and community services, about the handling, abatement, and management of asbestos in schools, the work place, and the home. Interpretation of the asbestos in schools requirements is also provided.

The Toxic Substances Control Act (TSCA) Assistance Information Service provides technical assistance and information about substances regulated under the act and also provides copies of some TSCA-related publications.
